It is essentially the expansion of these gas bubbles that causes an explosive eruption. e. high silica content) or if degassing has produced a large proportion of gas. The common analogy to illustrate the latter involves opening a bottle of carbonated spring water.

Degassing may begin with the release of small bubbles dispersed within the magma and expanding as the magma rises.

Perhaps the best known examples of igneous activity are volcanic eruptions resulting in molten rock reaching the ground surface or sea bed. The most common igneous rock resulting from volcanism is basalt. This dark coloured crystalline rock is the result of lava (molten rock on the Earth’s surface) solidifying. Granite is also a very common igneous rock; originating from the injection and solidification of large volumes of magma (molten rock below the Earth’s surface) into the crust. Granite is only exposed at the Earth’s surface in eroded mountain chains and in the roots of ancient mountain belts now preserved in the shield areas.
